Intelligent Light delivered a customized training session on the use and deployment of VisIt Prime, our new software and service package, at Tokyo University of Science. We have hardened and enhanced VisIt and now offer professional support from our global support team. The training - given by Brad Whitlock, a primary VisIt developer, and supported by Atsushi Toyoda, Ph. D. from our Asia Pacific Technical Office - introduced open source VisIt as a general purpose parallel visualization tool and VisIt Prime as the supported version from Intelligent Light. VisIt and VisIt Prime are supported by Intelligent Light, bringing our thirty years of experience in professional software delivery and support to the VisIt community.​

As CFD users increasingly exploit ultrascale HPC capability and approach the realm of exascale, they will run studies consisting of many related simulations at very high fidelity. This will give engineers and researchers both the ability and need to assess the quality of their simulations. When simulation quality has been vetted, engineering judgments and investment decisions can be made with confidence.

Uncertainty Quantification (UQ) provides a means to support this need and Intelligent Light has been working on integrating UQ tools including Sandia National Lab's Dakota in an extract-based (XDB) workflow where processing takes place while solutions are in memory and data storage/transfer needs are dramatically reduced.

Dr. Earl P. N. Duque will present "Uncertainty Quantification with Dakota-OVERFLOW within an in situ based FieldView XDB Workflow" at the Overset Grids Meeting. Meet with Dr. Duque and Joe Oliver, Global Sales Manager, to learn how FieldView users are getting more information from their data. Put the latest in high-productivity post-processing, in situ processing and CFD data management techniques to work for you.

Intelligent Light is proud to sponsor this year's symposium which will be held at the Future of Flight Aviation Center in Mukilteo, Washington on October 17-20, 2016.

NASA has called out the integration of VV/UQ tools into engineering workflows as a vital component of its "CFD Vision 2030 Study". In that document, the authors assert that as exascale computing becomes available, the capability to perform many highly resolved CFD simulations will become ubiquitous, enabling the ability, and need, to perform UQ and sensitivity analysis. To address this need, this presentation summarizes current work whereby the Dakota code drives an ensemble of OVERFLOW2 jobs to explore a nested epistemic-aleatory parameter space. Concurrently, OVERFLOW2 instrumented with VisIt/Libsim creates FieldView XDB surfaces via in situ processing to reduce the data for post-hoc visualization and analysis. The presentation presents UQ concepts in general and their implementation within the current framework.

This work is sponsored by a DOE Office of Science grant (DE-SC0015162)

Comparing many different CFD cases is often complicated by the use of differing meshes, solver codes and time intervals. Intelligent Light is working with CFD users in industry to develop and demonstrate engineered workflows to support the direct comparison of varied data.

The helicopter community seeks quality methods that allow for cost effective, accurate and timely simulations of hovering flight. The Helicopter Hover Prediction Workshop 2016 provides an opportunity to apply a standardized, automated post-processing workflow that eases dataset comparison, report generation and knowledge extraction for a diverse set of CFD results derived from varied models and solvers.

Dr. Earl P. N. Duque, Intelligent Light's Manager of Applied Research and Yves-Marie Lefebvre, FieldView Product Chief participated in the European Rotorcraft Forum September 5-8, 2016, in Lille, France. Dr. Duque presented in the aerodynamics track and the CFD workflow that enabled the work has applications for all CFD users.

​Direct comparisons of the CFD simulation results and the standardized post-processing scheme based upon FieldView will be demonstrated.The workflow tracks the helicopter rotor tip vortex core for quantitative comparisons while Iso-surfaces and coordinate cut planes of Q-criterion were created and saved as FieldView XDB files for qualitative comparisons. These surface extracts allow interactive viewing and direct comparisons of the predicted wakes using multi window graphical displays.

Special thanks to our partners at R Systems and Cray, Inc. for their support.

Intelligent Light will deliver a customized training session for the use and deployment of VisIt Prime, our new software and service package. We have been at work hardening and developing VisIt to become a useful and reliable engineering tool with top notch commercial support. Leading CFD customers in Japan will receive training from Brad Whitlock, a primary VisIt developer. Mr. Whitlock offers his expertise in the use of in situ processing for HPC environments and educate trainees in the use of both VisIt and Libsim for in situ processing.
